中文摘要: 以废旧石英坩埚为原料,在850 ℃的CaCl2熔盐中直接电解制备硅粉。采用XRD﹑SEM和ICP-AES对粉体进行表征和杂质含量检测。结果表明,电解后的粉体为呈准球形的单质硅,硼﹑磷杂质含量低,适合于制备太阳能级硅。
Abstract:Silicon powder was prepared by electrolysis in 850 ℃ molten salt with waste quartz crucible as raw materials. The powders were characterized by XRD and SEM and the impurities were analyzed with ICP-AES. The results show that in form of silicon as an element with torispherical particles and low impurity contents of boron and phosphorus, the electrolysis powder meets the requirements of SOG-Si production.
keywords: quartz molten salt electrolysis silicon solar energy
